唉!不定式的进行式到底是什么东西.谢谢

说起进行式，你来比较一下吧，希望对你有帮助*^-^*

不定式的形式：（以动词write为例）

否定式：not + (to) do

（1）一般式：不定式的一般式所表示的动作与谓语动词动作同时发生或发生在谓语动词动作之后，
例如：

I'm glad to meet you.

He seems to know a lot.

We plan to pay a visit.

He wants to be an artist.

The patient asked to be operated on at once.

The teacher ordered the work to be done.

（2）进行式：不定式的进行式所表示的动作与谓语动词动作同时发生，例如：

The boy pretended to be working hard.

He seems to be reading in his room.

（3）完成式：不定式的完成式表示的动作发生在谓语动词动作之前，例如：

I regretted to have told a lie.

I happened to have seen the film.

He is pleased to have met his friend.

不定时的进行时

好像是 to doing

可以这么理解吗 ?

我上学这么多年都不知道有这种说法哦

o(∩_∩)o...哈哈 晕了!~
